A woman I knew became Christian as an adult. Unlike some of us lifelong Christians who can be oblivious of the strangeness of our faith, she was appalled by one of the Beatitudes. 

Even now there are people in the Church who use rigidity to cover-up their own sins. That was the warning of Pope Francis at the morning Mass at the Casa Santa Marta. Commenting on the first Reading, from the Acts of the Apostles, the Pope focused on the figure of Saint Paul who, from being a rigid persecutor, became a meek and patient proclaimer of the Gospel.
